I have a 2005 CBR600rr. just put in new battey and it ran

Customer Question

I have a 2005 CBR600rr. just put in new battey and it ran fine for like a month or so. then it started to stall a few seconds or so after i would start it. I only have like 650 miles on it. I even turned the idle speed knob down on the left side, both ways. I con ride it still but i have to keep RPM's up so it wont stall if i come to a place i have to stop. Up till this issue it idled perfectly when stopped. So, i dont knowif the new battery is causing this or some other thing in the bike? Thanks for your time on my inquiry. I just want to be riding with out having to sit at stop light or sign revving it. thank you, ***** ***** email is (*****@******.***)

Hi and welcome back to JustAnswer,
Thank you for the question and your patience. Should you still need assistance for information purposes only...
Initially, and if have not been tried; inspect the battery & ground lines and/or check/clean the battery cables + terminals as a preliminary consideration. Better yet, have the battery externally charged and then LOAD TESTed (even if new and just for the purpose of eliminating it as a suspect).
Additionally, proposed further checks (again if have not been done) on the possibility of over-voltage/under-voltage. With a volt/multi-meter, determine the battery voltage when:
• ignition OFF and then when ON;
• when starting the engine;
• engine at idle;
• when attempting to rev the engine.
Please post back results / observations of the above once tried.
